Of course, that contact was not the cause - but didn't someone above point out the "bad" call ended up worse for Seattle?
Two different situations. The one I'm referring to was a play where Pittsbugh was (correctly) ruled to have recovered a Hasslebeck fumble, and then the play was (incorrectly) overturned on replay because of a bad "down by contact" call.
The other case was where a receiver caught and then fumbled a ball that was ruled incomplete (no chance for review). While some may say that because the ball eventually went out of bounds, this actually went against Seattle, the only reason the ball was let go out of bounds was that players pulled up when they heard the whistle.
